Patent GB-709108-A (GB)
Title: Procaine penicillin compositions
IPC: A61K31/43
Filed: 1951-02-27
Abstract: Granules containing procaine penicillin which are readily dispersible in water to give an injectable suspension, are prepared by grinding a mixture of procaine penicillin and a water-soluble salt of penicillin until it has a particle size between 50 and 150m , then adding thereto an organic solvent to form a paste, forcing the paste through a sieve and freeing the granules so formed from the organic solvent. The organic solvents are preferably non-solvents for the penicillin salts, e.g. acetone, methyl ethyl ketone, petroleum ether, n-hexane, dithyl ether, di-isopropyl ether, beta methoxyethanol, dioxan and diethyl carbonate.  Optional ingredients which are incorporated in the penicillin salt mixture prior to grinding are (a) non-ionic surface active agents such as condensation products of alkyl phenols with ethylene oxide or of sorbitan mono-oleate, -stearate, -palmitate or -laurate with ethylene oxide; (b) buffers, e.g. sodium citrate, and (c) bacteriostatic agents, e.g. phenyl-mecuric acetate.  In the case of (a) and (e), it is preferred to incorporate these substances in the presence of an organic solvent, which is a non-solvent for the penicillin salts, and to remove the solvent prior to the grinding operation.

Abstract: Surfaces of aluminium are coated with a vinyl resin by applying firstly a lacquer containing a copolymer of vinyl acetate, vinyl chloride and maleic acid and also an epoxy resin of low molecular weight, drying that coat, then applying a paste of a vinyl resin. The lacquer may also contain chromic acid, phosphoric acid, one or more organic hydroxy acids or esters thereof, or the condensation product of terephthalic acid, a glycol and a triol.  If applied by dipping or spraying, the compositions may be thinned with petrol.  If the top coat is of spongy vinyl resin a further coat of non-porous resin may be applied.ALSO:A lacquer for application to aluminium surfaces to cause a subsequently-applied vinyl resin to adhere thereto contains a copolymer of vinyl acetate, vinyl chloride and maleic acid and also an epoxy resin of low molecular weight; optional ingredients are chromic acid, phosphoric acid and one or more hydroxy acids or esters thereof (e.g. salicylic or lactic acid), or the condesation product of terephthalic acid, a glycol (e.g. 1,7-heptane diol), and a triol (e.g. glycerol).  The composition may contain solvents (e.g. toluene, and methyl ethyl- or methyl isobutylketones) and plasticizers such as dioctyl phthalate, butyl glycolate and the methyl ether of glycol monoacetate.  No information is given about the epoxy resin used.

Title: System for and method of destroying aqueous slurries containing combustible organic waste materials
IPC: F23G7/00
Filed: 1963-02-06
Abstract: 1,030,231. Burning refuse. GENERAL AMERICAN TRANSPORTATION CORPORATION. Feb. 6, 1963 [March 12, 1962], No. 4804/63. Heading F4B. An aqueous slurry containing combustible organic waste is burnt in a bed of refractory material 130 which is fluidized by an inlet stream of oxygen containing gas and maintained at such a temperature that the water in the slurry is evaporated and the waste burned within the bed. The fluidized bed 130 is supported on a lower layer of coarse fire brick 130a resting on a refractory grate 131. Air is delivered to a lower chamber 102a and passes to a chamber 102b containing a burner 193 to raise the temperature of the bed 130 for starting the process. The steam and gases from the bed 130 are completely burned in an upper part 120 of greater diameter than the bed 130, and pass through a dust separator 180 (Fig. 2, not shown), to the inner tube of a heat exchanger 270 which heats the combustion air. The gases pass through fresh slurry in an evaporator 240 to a condenser and stack (Fig. 3, not shown). The slurry, which may be sewage sludge mixed with ground garbage, is passed through screens to remove oversize solids and a mixer to the evaporator 240, where a sludge containing 3-10% by weight of combustible solids is concentrated to give a sludge containing 8-25% by weight of solids. By regulating the supply of sludge and air, the temperature of the fluidized bed can be maintained at between 1,300-1,800‹ F. without the further use of the burner 193.

Title: Improvements in or relating to fluid pressure indicators for pneumatic tyres and other inflated bodies
IPC: B60C23/00
Filed: 1932-02-18
Abstract: 392,310. Road-side tyre-inflating plant. TURNER & BRO., Ltd., W. and TURNER, W., 44, Eyre Lane, Sheffield. Feb. 18, 1932, No. 4872. Addition to 381,251. [Class 116.] The tyre - inflating installation of the parent Specification is provided with an audible alarm held inoperative during inflation, but becoming operative when inflation is nearing completion. The air on its passage from the source of pressure to the tyre passes through a pipe A into a chamber B to impinge on a float C which has connected to it a switch arm E which is also pivoted to a lug B<1> inside the chamber. The switch arm is thus kept out of engagement with its co-operating contact F until the required pressure in the tyre is nearly attained when the reduced velocity of the stream of air is insufficient to keep the contacts E, F open. The circuit is then made and an electric bell is sounded until the control knob of the apparatus is returned to zero, which is also arranged to break the alarm circuit. A whistle or other fluid pressure device may be operated by the float.

Abstract: 820,719. Making bellows and corrugated tubes; stamping. BAKER & SONS Ltd., P. W. March 3, 1958 [Feb. 13, 1957], No. 4956/57. Classes 83 (2) and 83 (4). Apparatus for forming bellows comprises two sets of die-plates 1, each forming half a complete die, each dieplate being of rectangular form and having extending at right-angles from the back edge thereof a rectangular guide - plate 2, said guide-plates being adapted to slide on each other and adjacent ones being connected together by a pin and slot connection to ensure the correct initial spacing of the dies. The operative edges of the dieplates have coacting bevel edges 3 and 4 to provide interlocking. The guide-plates and dieplates are carried in jaws 11 and 12 urged apart by springs 13 and 14. Cam surfaces 15 and 16 on the jaws co-operate with similar cam surfaces 17 and 18 fixed to a crosshead 19 movable with a ram 20 to close the dies around a tube inserted in the apparatus. When hydraulic pressure is applied to the tube the dies collapse longitudinally to form the bellows after which the ram is retracted and the springs open the dies radially. Extension-rods 21 and 22 fitted to the end guide-plates 10 are moved by the retreating ram to open the dies longitudinally. A lost-motion connection between the rods and the ram crosshead ensures that the dies are not extended longitudinally until they have been withdrawn radially clear of the finished bellows.
